[origin: EP0663555A1] A fluid tight union assembly for connecting together two tubes (13 and 14) or two tubular members such as a tube (107) and a tubular fitting (106), comprising a sleeve (10 or 100), a first end portion of which is concentrically disposed around the end of the tube and a collar (25 or 101), wherein the external surface of the end of the tube has a series of spaced ring joints and a first end portion of the sleeve has an internal surface with a series of spaced circumferential lands (15) which are engaged in the ring joints, the first end portion of the sleeve having a tapered external surface portion (20) which decreases in diameter towards the first end of the sleeve and in which a raised lip (24) on the external surface of the sleeve is engaged by a ring (27) and a slot (28) on the internal surface of the collar, firmly to retain the collar on the sleeve. If two tubes are being joined, then a double ended sleeve is used with two collars. <IMAGE>
